Hackers Crackers have attempted to topple key parts of the internet's backbone, in one of the most significant attacks of recent years. The target was servers that help to direct global internet traffic. In the early hours of Tuesday three key servers were hit by a barrage of data in what is known as a distributed denial-of-service attack. There is no evidence so far of damage, which experts are saying is testament to the robust nature of the internet.

Last time I checked more of the Internet's big DNS (and BIND) servers were running some variant of Unix.

I think it's time we question whether Unix is an appropriate platform for the Internet. This is not the first time this has happened, and if we keep using in-secure OSes for critical data then we get what we deserve.
